EXERCISlNG-MACHINE.

SPECIFICATION formingpart of Letters Patent No. 433,960, dated August 12, 1890.

Application filed March 1, 1850.

To aZZ whom it may concern.-

Be it known that I, LEE J. PENNOCK, a citizen of the United States, residing at Brooklyn, in the county of Kings, State of New York, have invented certain new and useful. Improvements in Exercising Machines, of which the following is a specification, reference being had therein to theaccompanying drawings.

The apparatus when properly rigged will serve as a rowing apparatus, which may be used in private houses or in gymnastic halls; and the object of my invention is to produce a simple and strong device having a pivoted cylinder embraced with two metal bands placed one above the other to produce thereon the necessary friction, and also to permit said frictional'device or the oar attached thereto to be rocked to allow the ordinary motions of an oarsman to be performed with the device.

I attain these objects by the construction illustrated in the accompanying drawings, in p which Figure 1 is a top view of the friction-clutches and bearing thereof constructed in accordance with my invention.' Fig. 2 is a vertical central section of the same partly broken away to show the attachment of one of the frictionbands. Fig. 3 represents in top view a modi- 3o fication of the hea of the clutch-lever. Fig. 4 is a side view of the inner cylinder of the clutches and the outrigger carrying it, the inner end of said outrigger and its lateral brace being shown connected to the gunwale of a boator frame of the exercising-machine represented in plan. Fig. 5 represents horizontal sections through the outrigger-socket and the outrigger. Fig. 6 is a transverse section through a portion of the supportingframe with the outrigger, the clutch-bearing plate, and central bolt in elevation.

In said drawings, A represents the base plate of the clamping and clutching devices. Upon said plate there is placed a cylinder 0, that is centrally perforated, and has passing therethrough abolt B, that connects it to the base-plate and to one end of the outrigger-D. The surface of the cylinder is divided horizontally into two parts by an encircling rib c.

To prevent the free rotation of the cylinder serial No. 342,217. (No model.)

C, a band E is passed nearly around the same, and to the ends thereof are secured in asuitable way the shoes E, which are provided with angular arms E E which extend outwardly between the lugs a a on the plate A, so that said arms normally abut against the sides of said lugs, whereby the band is held in frictional contact with the cylinder. The frictional cont-act is increased by means of a set-screw a, passed through the lug a and bearing against the arm E so that by giving to the screw to a fourth, or even an eighth or a tenth of a turn the friction of the band E upon the cylinder O is materially increased.

To obtain sufficient force to rotate the cylinder, a clutch-band F is made to encircle nearly the whole of its periphery above the middle rib 0. Each end of the clutch-band is bent over to form a loop f, throughwhich is passed a screw or rivet g g whereby it is connected to the upper and lower arms of the eccentrically-mounted head G of the clutch. lever or oar G Said head G is suspended from' abolt h, passing vertically through a hole 9 therein, the upper portion of this bolt pass- 7 5 ing through the outer end of a link I, that has its inner end retained upon the cylinder 0 by the central bolt 13. The bolt h has a shoulder if to abut against the under side of the link, and a nut 71 on the upper end of the bolt h retains the latter immovably attached to the link.

From the location of the band-retaining screws g g it will be seen that by pulling, the oar in the direction of the arrow in Fig. 1 it will have a tendency to tighten the clutchband F around the cylinder O and revolve it in the direction shown by the arrow upon said cylinder; but the reverse motion will release the clutch-band from the cylinder.

To prevent an excessive lost motion of the oar when the operator pushes it away from him to take a new stroke, a set-screw k is inserted horizontally in alug G projecting upon the top of the head G, so that its point will 95 impinge against the side of the link I and prevent too great a slackening of the band F. The lever G which has also been called the car, is to be inserted in the handle of a wooden oar, as usual.

To permit a dipping motion to be made with the oar, said oar G may be hinged to the head G, as shown in Fig. 3. For this purpose said head has two ears 9 to receive a pivot-screw g that passes through the inner end of the oar, the ears 9 acting also as lateral braces for said inner end. This same dipping motion is obtained by making the outrigger D of two lengths, as shown in Figs. 4 and 6, said lengths being hinged together at d at a short distance from the clutch-support. Said outrigger is preferably made of T-iron. To facilitate the disconnection of the outrigger from its supporting-frame L, there is attached to the side of said frame a socket .M, having a T-shaped opening therein to receive the inner end of the outrigger. To properly brace the clutch or the outer end of the outrigger laterally to the supporting-frame L, two rods 71, have one end secured to lugs (1 pendent from the outrigger at points beyond the hinge, as shown by the rods am full lines, or at points on the inner side of said hinge, as shown by the rods n in dotted lines. In either case the inner ends of said rods are secured to eyebolts N, attached to the side of the frame L. The two means shown to permit the dipping motion of the oar can be used either separately or together on the apparatus. Having now fully described my invention, I claim- 1. In an exercising-machine, the combination of the supporting-plate A, having lugs upon its surface, a cylinder pivoted to said end inserted in said socket and the outer part having a cylinder pivoted thereto with an car, a link connecting said oar with the pivot-bolt of the cylinder, and a metal band around said cylinder, said band having its ends secured to said oar, substantially as de scribed.

3. In an exercising-machine, the combination of an outrigger, a cylinder rotatably secured thereto and frictionally retained, a clutch-band around said cylinder, a link having one end retained upon the pivot-bolt of the cylinder, a head pivoted to the opposite end of the link and uniting the ends of the clutch-band, and a lever pivoted to said head, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

I LEE J. PENNOOK.
